Abstract : There are a number of alloys, which exhibit the shape memory effect; however, not all of them generate large strains or forces when activated. Two SMAs which generate large amounts of strain and are capable of generating a large force upon transformation back to the austenitic phase are nickel titanium (Ni-Ti) alloys and copper (Cu) based alloys such as Ti-Ni-Cu can recover up to 6% strain. TiNi alloys tend to be more thermally stable, ductile and corrosion resistant than the Cu based alloys. However the Cu based alloys are less expensive to produce and are easily melted and extruded in air with a larger range of transformation temperatures available. A comparison of the properties of TiNi, CuZnAl and CuAlNi can be found. Experiments have been conducted by varying the percentage of copper combination in Ni-Ti alloy, to find out the variation of hardness and the wear properties. It is understood with the increase of copper percentage; hardness has been increased resulted in the wear resistance characteristics.
